SHIELD FOR AUTO IJIIEADLIGHTS.

Application filed February 9, 1927. Serial No. 166,993.

The present invention relates to lamp shields especially designed for use in connection with motor vehicle headlights and aims to provide a device which may be readily and easily poxitioncd and supported on an electric lamp, the construction of the shield being such that the forward portion of the lamp will be completely guarded to deflect light rays laterally, rearwardly and downwardly, thereby eliminating glare.

An important object of the invention is to provide a shield including lateral adjustable deflecting means so constructed that they be moved with respect to the lamp on which the shield is supported, to meet various requirements.

A further object of the invention is to provide a device of this character which may be constructed of sheet metal by a single stamping operation, thereby reducing the cost of manufacture to the minimum, and at the same time providing a shield which may be shipped flat,'and bent to its proper position by the user.

l Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, 1t being understood. that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing: Figure l is a sectional View through a headlight showing a shield constructed in accordance with the invention as positioned therein.

Figure 2 is a sectional view through the shield.

Figure 3 is a rear elevational View of the shield. p V

Figure 4 is a bottom plan View thereof.

Figure 5 is a plan view of the blank from which the shield is constructed.

Referring to the drawing in detail, the reference character 5 indicates the body portion of the shield which is formed preferably of sheet metal, the rear edge of the body portion being slightly curved as at 6 to conform tothe curvature of the reflector of the headlight in which the device 1s positioned.

Formed at points substantially intern'iediate the ends of the body. portion and extending from the side edges of the body portion, are slits 7 that terminate at points in spaced relation with each other so that the forward portion of the body may be bent downwardly as clearly shown by Figure 2 of the drawing, defining a forward shield 8.

The free edge of the shield 8 lies in a. plane below the lower edge of the bulb supporting the shield so that the forward portion of the bulb or lamp will be completely shielded, to the end that a person approaching a lamp equipped with the shield would not be blinded by the light rays projected forwardly from the lamp. i

Due to the width of the body portion it will also be seen that the side edges of the shield 8 are disposed appreciable distances beyond the side edges of the lamp supporting the shield, so that a person approaching the headlight from an angle will not be blinded by the glare or light rays projected at the ends of the shield 8.

The portions 9 of the body portion, and formed by the slits 7 define lateral adjustable wings 10 which may be bent downwardly to cause light rays directed laterally from the lamp tobe projected downwardly. Due to this construction it will be seen that the wings 10 may be adjusted to Various angles with respect to the shield 8, at the will of the user.

An opening 11 is formed-in the body portion adjacent to the curved rear edge thereof, which opening is of suflicient size to allow only the upper portion of a lamp to proj ect therethrough so that light rays fromthe lamp may be directed upwardly to impinge on the upper reflector surface of the headlight from where the light rays will be directed forwardly. V

It might be further stated that the slits I tween the shield 8 and main body portion.

-7 are formed at oblique angles with respect I Rubber protectors such as indicated at 1 are positioned over the securing fingers so that the securing fingers will closely grip the base of an electric lamp to hold the device against movementwith I'GSDGCt t'l'iereto after it has been positioned.

it might he further stated that it is contemplated to construct the device of sheet metal having an inner reflecting surface, while the outer surface thereof is dull, however it is to be understood thatthe material of which the device is constructed may be provided with dull inner and outer surfaces, within the scope of the invention.

I claim:

A headlight shield including a body por-' the forward edge of the rear portion and the 7 side edges of the bodyportion being curved downwardly to shield the. sides of the lamp on which the shield is positioned.

In testimony that I claim the foregoing as my own, Ihave hereto atiixed my signa-,

ture.

GLENN PRATT.
